在植物的无机营养中,硼是一个必须的微量元素。土壤和农家肥料中都含有一定量的硼,因此在作物栽培上很少施用硼肥。近年来在全国很多地区发现某些作物有明显的缺硼病害,引起作物减产;如棉花缺硼不能形成棉桃,小麦缺硼穗子空瘪无籽粒和油菜“花而不实”症等。因此对推广使用硼肥引起重视,当前全国试用硼肥面积已达100万亩,并取得良好的效果。一、生产上施硼肥效果施用硼肥有效地防治了油菜“花而不实”症,显著地提高有效荚数和增加每荚粒数。
In plant inorganic nutrition, boron is an essential trace element. Soil and farmyard manure contain a certain amount of boron, so boron is rarely used in crop cultivation. In recent years, it has been found in some areas of the country that certain crops have obvious boron deficiency diseases that cause crop yield loss. For example, the lack of boron in cotton can not form cotton buds, and the wheat lack of boron panicles is empty and has no seeds and rape blossoms. Therefore, to promote the use of boron fertilizer attention, the current national trial of boron fertilizer area has reached 1000000 mus, and achieved good results. First, the production of boron fertilizer application of boron fertilizer effective prevention and control of the rape “flowers without real” disease, significantly increase the effective pods and increase the number of pods per pod.
